We know starting a building project in the UK can feel like stepping into a maze of rules, but that’s where we help. At Ratio Seven, we make building regulations simple to understand and easier to follow, whether you’re planning a new build, a loft conversion or a shop refit.
When you’re building anything from a small extension to a full development, staying on the right side of the rules makes a big difference, and that’s where we come in. We work with self-builders, architects and developers to make sure building regulations are followed from the start. That means giving
We get asked all the time what air pressure testing is and why it’s needed, so here’s the easy answer: it checks how much air leaks from your building. Too many gaps make your home cold and expensive to heat, and it can even stop you from passing building regulations.
Building compliance means making sure your project meets the rules set out in the UK’s Building Regulations, covering things like safety, ventilation, energy use and fire protection. We help you understand what those rules mean in real life, before the build starts, during the work, and when it’s time to
SAP Calculations are energy checks we do for homes across the UK, and they’re needed when building a new house, converting a space into a home, or adding a big extension. They show how much energy your home will use and if it meets rules on heating, lighting, and more.
At Ratio Seven, we test how airtight your building is by checking for any gaps where warm air might sneak out. It’s all about helping you keep heat inside, cut energy bills, and meet current building rules. We use a special fan to spot leaks and let you know what
When you're building or selling a home in the UK, you’ll probably hear about SAP assessments and they can sound a bit confusing at first. We help people understand what they mean and why they matter. A SAP assessment looks at how much energy a home will use and gives
Airtightness testing, also known as blower door testing, is pivotal in whole-building life cycle assessments, significantly influencing energy efficiency and operational emissions by minimising air leakage and reducing the need for heating and cooling. This testing is essential for Whole Life Carbon Assessments, as it mitigates operational carbon emissions by
Permeability testing, also known as air tightness testing, plays a vital role in enhancing energy efficiency by identifying and rectifying air leaks in buildings. In Leicester, this process is not only crucial for reducing energy wastage and operational costs but is also mandated under Building Regulations Part L1A, ensuring buildings
